Прямо сейчас, если я попытаюсь добавить несистемного пользователя, не входящего в университетскую область Kerberos, мне все равно будет предложено ввести пароль Kerberos. Очевидно, что вводить пароль не нужно, поэтому я просто нажимаю ввод и вижу:

passwd: Authentication token manipulation error
passwd: password unchanged

Набор текста passwd newuser такая же проблема с тем же сообщением.

Я пробовал использовать pwconv в надежде, что нужна только теневая запись, но это ничего не изменило.

Я хочу иметь возможность добавить локального пользователя не из области и дать ему локальный пароль, не беспокоясь о Kerberos.

Я использую Ubuntu 10.04. Вот мои /etc/pam.d/common-* файлы (значения по умолчанию, которые Ubuntu pam-auth-update пакет генерирует):
